* Launch Disk Utility * Select the Snow Leopard DVD within Disk Utility * Click the “New Image” button at the top * Name the image and put it somewhere you can find it easily (Desktop) * Click OK and wait for the image to be created Easy enough right?
Ok so here’s how you create a bootable Snow Leopard installation drive out of your external firewire or USB hard disk.
* Disabled “Wireless G only” Mode – what seems to have finally sealed the deal was disabling ‘Wireless G Only’ mode that I had set on my router, yea things could theoretically be a little slower but I haven’t noticed, and I’ll wait an extra millisecond or two for a webpage to load if it means I can use my Mac Book wirelessly at home as intended.
Interestingly enough, I tried doing each of these things entirely on it’s own and it did not resolve the problem, it was the combination of everything that seems to have ‘fixed’ my airport connection problems.
* Alternatively, you can select the Snow Leopard Install DVD and restore directly from the DVD to the GUID partition * After the restoration is complete, your GUID partition will now be bootable by Mac OS X!
* Reboot the Mac holding down the “Option” key to pull up the boot loader, select the Snow Leopard install drive you just created rather than your default Mac OS hard drive * Install Snow Leopard as usual!
Here’s what I did to fix my Airport wireless connection from dropping in Snow Leopard.
I don’t know why but when I upgraded to Snow Leopard my wireless internet got all wonky, connections were dropping left and right and I couldn’t maintain any worthwhile airport connection for longer than a few minutes.
DHCP was behaving particularly strange and the automatic settings pulled from my router were dropping every few seconds.
* Turn Airport on & off (via menu or Network preferences) * Delete and then recreate/reestablish wireless network connection * Create a new Network Location * Make sure your router firmware and Airport card firmware is up to date * Zap the PRAM on your Mac (hold Command Option P R on restart) * Flush the DNS cache using the Terminal command: dscacheutil -flushcache * Delete the com.apple.internetconfigpriv.plist and com.apple.internetconfig.plist files from ~/Library/Preferences * Trash your home directories System Configuration folder and reboot – Remove all files within ~/Library/Preferences/System Configuration/ and reboot your machine.
Make sure you delete the proper folder, this is in your home directory.
